Problems solved by technology

A general shop sign is not easily modified upon its manufacturing process being completed and thus unable to meet changing marketing demand.
Further, many plastic ropes C are needed to attach the soft tube lamp A to the iron frame B. Therefore, the manufacturing costs are increased due to much more time, work and materials.
The lighting equipments cannot do without the fixed plate body, so manufacturing cost is still high.
Once completed, the equipment is not modified easily and accordingly lacks of mobility.

Embodiment Construction

[0022] Please refer to FIG. 2 and FIG. 4. The tube lamp 1 of the present invention comprises a plastic tube 10 and a thicker metal wire 30, wherein:

[0023] the plastic 10 is a PVC tube having a power supply wire 20 inside the tube and a plurality of parallel connected light bulb sets 21, each light bulb set comprising a plurality of serially connected mini light bulbs 22.

[0024] The metal wire 30 is a flexible steel wire or copper wire with a thick diameter, is disposed inside the plastic tube 10, and parallels the power supply wire .

[0025] Referring to FIG. 3, one meter is the best length for each light bulb set 21 consisting of serially connected mini light bulbs 22. Each meter including mini light bulbs 22 is parallel connected with the power supply wire 20, thereby the tube lamp 1 is completed. When used, the tube lamp is cut for its appropriate total length. The tube lamp has one end sealed with a cover and the other end provided with the power supply wire 20, which is connected ...

Abstract

An improved structure of tube lamp comprises a plastic tube having a power supply wire inside the tube and a plurality of parallel connected light bulb sets, wherein the light bulb sets consist of a plurality of serially connected light bulbs; a thicker metal wire is disposed inside the tube, is bended as desired and parallels the power supply wire, whereby the tube lamp is easily bended into a different model without any assistant frame. For any purpose, e.g. advertisements or festivals, construction is facilitated, cost is reduced and reusability is enhanced.

Description

[0001] 1. Field of the Invention[0002] The invention is an improved structure of tube lamp at substantially lowered cost and offers various models. It is used for any purpose, e.g. advertisements, shop signs, festivals and decorations.[0003] 2. Descriptions of the Prior Art[0004] A general shop sign is not easily modified upon its manufacturing process being completed and thus unable to meet changing marketing demand. To overcome this defect, a traditional soft tube lamp includes a plastic tube having a power supply wire inside and multiple parallel connected light bulb sections each light bulb sections includes multiple serially connected light bulbs at intervals. As shown in FIG. 1, before the soft tube lamp A being bended into different models, a iron frame B with the specific shape is made, welded and roast painted. Further, many plastic ropes C are needed to attach the soft tube lamp A to the iron frame B. Therefore, the manufacturing costs are increased due to much more time, ...
